Thanks, I check the white terminal and found the correct wire

Hello, I guess the 2021 GMC Sierra changed up things a bit. I do not have the grey wire coming out of the white plug., Have anyone put the foot well lights on the 2021 truck, if so what wire did you use and the location. Strange thing is when I disconnect the plug the lights goes out on the dome, but I cannot find the individual wire that controls the light. Help!
